Leds blinking like crazy

Recommended Posts



i have started my UM2(with + upgrade) printer today and the leds on the left side were blinking. They still blink.

Is there anything i can check to fix this problem ?

I'm not sure what you mean.  When the bed gets up to temperature they flash about 20 to 50 times per second.  Most people don't notice this.  Is this what you mean or even when you first turned it on?  If it's flashing when you first turn it on (but not the bed heater is off) then it's probably a bad wire or bad LED strip.  The wiring can get caught in the belt and pulley system.

The leds blink all the time, until I shut off the printer. I can even print a piece and leds are happily blinkg all the way. It affects only the left vertical side. The top and right leds do not blink. Is it easy to replace these led strips ?

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
